OBJECTIVES To determine the mechanism of antimicrobial action of lactocin 160, a bacteriocin produced by the healthy vaginal strain of Lactobacillus rhamnosus, using an established model, with Micrococcus luteus ATCC 10420 as a test organism. METHODS Sensitivity of M. luteus to lactocin 160 was determined by the diffusion assay. Loss of cellular ATP in the lactocin-treated cells was elucidate...

Objectives. To determine the mechanism of antimicrobial action of lactocin 160, a bacteriocin produced by the healthy vaginal strain of Lactobacillus rhamnosus, using an established model, with Micrococcus luteus ATCC 10420 as a test organism. Methods. Sensitivity of M. luteus to lactocin 160 was determined by the diffusion assay. Loss of cellular ATP in the lactocintreated cells was elucidated...

In this paper, we present an event detection system evaluated in 2015 TRECVID-SED. The system consists of two parts: automatic event detection (retrospective) and interactive event detection with human in the loop (interactive). For the retrospective part, an extended spatio-temporal features, MoSIFT, is extracted, and two types of temporal divisions (annotation partition and sliding window) ar...

We have used the sub-millimeter array to image the molecular envelope around IRC+10420. Our observations reveal a large and clumpy expanding envelope around the star. The molecular envelope shows a clear asymmetry in CO J=2–1 emission in the South-West direction. The elongation of the envelope is found even more pronounced in the emission of CO J=2–1 and SO JK=65–54. A small positional velocity...

The yellow hypergiants are found in a stage between the massive Red Supergiants and the Wolf-Rayet stars. This review addresses current issues concerning the evolution of massive stars, concentrating on the transitional postRed Supergiant phase. Few yellow hypergiants are known and even fewer show direct evidence for having evolved off the Red Supergiant branch. Indeed, only two such rare objec...
